FUNCTION: DisplayOutput

DESCRIPTION
    This function displays an output string at a given line number on the
    screen. If the nline parameter is a negative value (-1) the string
    is displayed in the middle of the screen. If the "nline" value is larger
    than or equal to zero the "nline" value is multiplied by 15 and the 
    resulting value in pixels is set to the y-coordinate of the start of 
    the string display on the screen. If the string does not fit on one line
    the string wraps around to the next line (spaced rougly 10-15 pixels apart).
    By default 5 is used as the starting the x-coordinate of a displayed 
    string.

    How many characters that fit on one line is calculated for each line 
    that is wrapped around to the next line.

    Note: depending on the phone screen size and the fonts used for characters 
          the output might differ on different handsets (devices). Where some 
          handsets will have a smaller screen and large default fonts which will 
          cause partial overlapping of lines. This function does not try to address
          these issues (this is meant as a simple display function).
    
PROTOTYPE:
   int DisplayOutput(IShell *pIShell, IDisplay *pDisplay, int nline, char *pszStr, AECHAR *pszwStr, boolean isWideChar)

PARAMETERS:
   pIShell:   [in]: Contains a pointer to the IShell interface.
   pIDisplay: [in]: Contains a pointer to the IDisplay interface.
   nline:     [in]: Contains the line number to start displaying the text. The line
        numbers are by default spaced 15 pixels apart along the y-axis.
   pszStr:    [in]: The character string to be displayed on the screen.

DEPENDENCIES
  None

RETURN VALUE
  Number of lines written to the screen.
